NASA has revealed the crew for its Artemis III mission, the next step in eventually landing astronauts on the moon. NASA’s Randy Bresnik, Frank Rubio, Andre Douglas and the European Space Agency’s Luca Parmitano won’t fly to the moon or land on the surface. Instead, they’ll orbit Earth while practicing docking their Orion capsule with lunar landers. The demo is targeted for 2027. NASA’s Artemis program aims to land astronauts on the moon for the first time since the 1970s.

Astronauts aboard the International Space Station have briefly taken shelter during a repair to fix a new leak. The five astronauts moved to the docked SpaceX capsule on Friday while cosmonauts worked to fix the leak on the Russian side of the orbiting laboratory. NASA says this was done “out of an abundance of caution.” That part of the space station has suffered from cracks and leaks over the years. NASA said Roscosmos decided on a more extensive repair after fresh leaks were found. The astronauts were allowed to leave the capsule after repair work was paused.

NASA's Maven spacecraft around Mars has been declared dead after six months of radio silence. Maven was launched in 2013 to study the red planet's atmosphere. It fell silent in December after passing behind Mars. NASA confirmed Wednesday that the mission is over. Data indicated that the spacecraft went into a fast spin, which disrupted its orbit and drained the onboard batteries. A review board convened by NASA earlier this year concluded that the spacecraft is useless and unable to be recovered. Besides studying Martian weather, Maven helped relay information from NASA's Curiosity and Perseverance rovers on the surface.
